Sunny Health & Fitness SF-RB921 Magnetic Recumbent Bike

The Sunny Health & Fitness SF-RB921 is an easy-to-use machine that is especially geared towards beginners and intermediate users. Ideal for users who are on a limited budget, the Sunny recumbent bike only costs between $100 and $200. This particular model comes with only the basic features, and has also the advantage of being quite lightweight, enabling you to carry it to just about any room of the house. More importantly, this machine provides you with an ergonomic posture that will allow you to work out without feeling fatigued. In fact, according to fitness experts, it is best to go for recumbent bikes because they drastically decrease the risk of strains and other sports-related issues like slipped discs and lower back pain.

Comfort Level

This particular model provides a decent level of comfort for its price. For example, it comes with large pedals that come with large rubber straps that can be adjusted around different ankle sizes. The pedals are thickly textured to provide a reliable grip.

Since the seat keeps your body in a semi-horizontal position, your weight is evenly distributed which means less stress on your joints. The recumbent seat also keeps your legs extended for added comfort. The seat is lightly padded which can provide adequate comfort for around an hour or so. If you’re planning on using the machine for longer periods of times, you might want to place a cushion on the seat for more comfort. The armrests are widely spaced to provide ample room for overweight users. However, significantly obese people might have an issue with the space between the seat and backrest.

This bike also has a “Step-Through” design, which saves you the hassle of having to hoist yourself up the saddle when you have mobility issues. This is also convenient for obese users. Therefore, users simply need to step into the bike instead of trying to climb up. Unlike other Sunny Health and Fitness models, such as the Sunny Pink and the Sunny Folding, this particular bike comes with a decent maximum user capacity of 265 pounds.

The majority of customers found that they only needed around forty-five minutes to an hour to it set up.

Drawbacks

Other people claimed that the machine occasionally got noisy, in spite of the heavy flywheel.
